Congratulations on space success

Comment on "An inspiring mission" (China Daily, June 30)

I wish to congratulate China for the success of its Shenzhou IX space mission and particularly the astronauts who made it possible, especially Liu Yang, China's first female astronaut.

But it is worth considering that other frontiers need exploring, not just outer space, but also inner space, the universe found within ourselves.
